Abstract
A strip of riveted belt fasteners is provided manufactured in a punch press or the like to form multiple belt fasteners at a time with the fasteners each being attached to an end of a conveyor belt by way of a single rivet extending through single apertures in upper and lower plates of each of the fasteners. The small fasteners herein are provided with sufficient strength to be used in abusive hay baler applications while the fasteners must travel about small pulleys, e.g. 3″ to 3.5″ inches in diameter. Further, the installation of this rivet belt fastener in the field is about as simple as driving a nail requiring a portable applicator tool and a hammer. That is, the fasteners can be riveted attached to the belt end by way of a low cost applicator tool that includes recessed hardened anvil surfaces integrally formed in the body thereof to upset initially rivets which are driven through the belt with a separably attached pilot nail. The hollow rivet end flares out against the hardened anvil surfaces of the tool with the surfaces being inclined for curling of the rivet end back up into an enlarged recess in the overlying plate aperture. As the rivet is driven, the belt compresses with the rivet end being upset; and upon removal of the driving force, the belt decompresses to draw the curled, upset rivet end into the plate aperture.
